Summary
In the past few years, significant progress has been made in modeling and state estimation for industrial processes to improve control performance, reliable monitoring, quick and accurate fault detection, diagnosis, high product quality, fule and resource consumption, etc. However, with the fast development of information technology, numerous essential issues are facing in modeling and state estimation, which generates the new need for novel modeling and or state estimation methodologies and in-depth studies of them.
For example, due to many online sensors equipped, measurements are commonly collected with the characterizes of high volume, velocity, and variety. Therefore, feature selection or dimension reduction that extracts the signal interested and removes redundant information will be more critical during modeling than before, which will, in turn, affect the modeling and estimation algorithmic performance. Fast operation and high computational efficiency of an algorithm matter more since data often arrive rapidly, and the target values are usually required in an online manner. Besides, high accurate estimates of key parameters become more critical since reliable and precise modeling plays a vital role in many tasks, including control, detection, and monitoring. All these challenge the current statistical signal processing techniques from applicability, computational efficiency, and effectiveness. This special issue aims to bring the researchers in this area together with the engineers to break down barriers and develop innovative solutions and practical algorithms.

Rebecca Gedda, Larisa Beilina, Ruomu Tan
CMES-Computer Modeling in Engineering & Sciences, Vol.134, No.3, pp. 1737-1759, 2023, DOI:10.32604/cmes.2022.019764

Abstract Change point detection becomes increasingly important because it can support data analysis by providing labels to the data in an unsupervised manner. In the context of process data analytics, change points in the time series of process variables may have an important indication about the process operation. For example, in a batch process, the change points can correspond to the operations and phases defined by the batch recipe. Hence identifying change points can assist labelling the time series data. Various unsupervised algorithms have been developed for change point detection, including the optimisation approach which minimises a cost function with certain…

Abstract To provide stable and accurate position information of control points in a complex coastal environment, an adaptive iterated extended Kalman filter (AIEKF) for fixed-point positioning integrating global navigation satellite system, inertial navigation system, and ultra wide band (UWB) is proposed. In this method, the switched global navigation satellite system (GNSS) and UWB measurement are used as the measurement of the proposed filter. For the data fusion filter, the expectation-maximization (EM) based IEKF is used as the forward filter, then, the Rauch-Tung-Striebel smoother for IEKF filter’s result smoothing. Tests illustrate that the proposed AIEKF is able to provide an accurate estimation.

Abstract In this paper, a self-triggered consensus filtering is developed for a class of discrete-time distributed filtering
systems. Different from existing event-triggered filtering, the self-triggered one does not require to continuously
judge the trigger condition at each sampling instant and can save computational burden while achieving good
state estimation. The triggering policy is presented for pre-computing the next execution time for measurements
according to the filter’s own data and the latest released data of its neighbors at the current time. However, a
challenging problem is that data will be asynchronously transmitted within the filtering network because each
node self-triggers independently. Therefore,…

Abstract This paper studies the parameter estimation problems of the nonlinear systems described by the bilinear state space
models in the presence of disturbances. A bilinear state observer is designed for deriving identification algorithms
to estimate the state variables using the input-output data. Based on the bilinear state observer, a novel gradient
iterative algorithm is derived for estimating the parameters of the bilinear systems by means of the continuous
mixed
p-norm cost function. The gain at each iterative step adapts to the data quality so that the algorithm has
good robustness to the noise disturbance. Furthermore, to improve the performance of…

Abstract In this paper, an improved high-order model-free adaptive iterative control (IHOMFAILC) method for a class of
nonlinear discrete-time systems is proposed based on the compact format dynamic linearization method. This
method adds the differential of tracking error in the criteria function to compensate for the effect of the random
disturbance. Meanwhile, a high-order estimation algorithm is used to estimate the value of pseudo partial derivative
(PPD), that is, the current value of PPD is updated by that of previous iterations. Thus the rapid convergence of the
maximum tracking error is not limited by the initial value of PPD. The convergence…

Abstract In modern industry, process monitoring plays a significant role in improving the quality of process conduct. With
the higher dimensional of the industrial data, the monitoring methods based on the latent variables have been
widely applied in order to decrease the wasting of the industrial database. Nevertheless, these latent variables do
not usually follow the Gaussian distribution and thus perform unsuitable when applying some statistics indices,
especially the T2 on them. Variational AutoEncoders (VAE), an unsupervised deep learning algorithm using the
hierarchy study method, has the ability to make the latent variables follow the Gaussian distribution. The partial
least squares…

Abstract This paper is focused on the state estimation problem for nonlinear systems with unknown statistics of measurement noise. Based on the cubature Kalman filter, we propose a new nonlinear filtering algorithm that employs a
skew t distribution to characterize the asymmetry of the measurement noise. The system states and the statistics
of skew t noise distribution, including the shape matrix, the scale matrix, and the degree of freedom (DOF) are
estimated jointly by employing variational Bayesian (VB) inference. The proposed method is validated in a target
tracking example. Results of the simulation indicate that the proposed nonlinear filter can perform…

Abstract For improving the localization accuracy, a multi-interval extended finite impulse response (EFIR)-based RauchTung-Striebel (R-T-S) smoother is proposed for the range-only ultra wide band (UWB) simultaneous localization
and mapping (SLAM) for robot localization. In this mode, the EFIR R-T-S (ERTS) smoother employs EFIR filter
as the forward filter and the R-T-S smoothing method to smooth the EFIR filter’s output. When the east or the
north position is considered as stance, the ERTS is used to smooth the position directly. Moreover, the estimation
of the UWB Reference Nodes’ (RNs’) position is smoothed by the R-T-S smooth method in parallel. The test
